An old Lady came to a pet shop to buy a parrot. A saleswoman shows her a parrot that has a green ribbon tied to one leg and a red ribbon to the another.
The old woman got curious and asked what the ribbons were for.
- when you pull the green ribbon, the parrot speaks French, but when you pull the red ribbon, it speaks English - replied the salesgirl.
- and what if I pull both of them?
- Then I'll fall off the pole, you old idiot, squawked the parrot.
